Features Settings

Unless otherwise specified on the order, the controller features settings are set at the factory to the default values. If a setting must be changed, follow the procedure on the next page. Some settings may require a password (if the controller is set up for one).

Any indiscriminate change in these settings may affect the normal operation of the Automatic Trans- fer Switch. This change could allow the load circuits to remain connected to an inadequate source.
